23rd International Symposium of the International Scientific Centre of Fertilizers Plant nutrition and fertilizer issues for the cold climates Son (Norway), September 8-10, 2015   The significance of sulfur nutrition and metabolism in the detoxification of excessive levels of copper, zinc and molybdenum in plants  Luit J.

Box 11103, 9700 CC Groningen, The Netherlands, l.j.de.kok@rug.nl  Copper, zinc, manganese and molybdenum are essential plant nutrients, however, elevated concentrations of these metals in the root environment are potentially phytotoxic and may disturb metabolic functioning and plant biomass production. The primary cause of their phytotoxicity is still largely unresolved. Exposure of plants to excessive levels of toxic metals may interfere with the regulation of uptake, reduction and assimilation of sulfur in plants. They might compete with the uptake and reduction of sulfate (e.g. MoO42-) or react with sulfur metabolites and/or induce the formation of sulfur-rich proteins and peptides (e.g. Cu2+, Zn+), which might be involved in metal sequestration in order to avoid disturbance of cellular homeostasis of these metals. The impact of elevated Cu2+, Mn2+, MoO42- and Zn2+ concentrations in the root environment on physiological functioning and uptake, distribution, reduction and assimilation of sulfur was studied in detail in Brassicaceae. This in order to get more insight into the physiological background of the toxicity of high tissue levels of these essential metals, and the significance of sulfur nutrition and metabolism in their detoxification.      4 Berichte aus dem Julius Kühn-Institut 184, 2016
